Overview
MC9S08PT16VTJ from NXP Semiconductors is an 8-bit S08 microcontroller with 16 KB flash, 2 KB RAM, and 256 B EEPROM, operating at up to 20 MHz across –40 °C to 105 °C. It integrates dual FlexTimer modules (6-channel + 2-channel), 12-bit 12-channel ADC, I²C, two SCI/UARTs, SPI, RTC, and touch-sensing interface (TSI), targeting industrial motor control and sensor-based embedded systems.
For engineers reviewing the MC9S08PT16VTJ datasheet, MC9S08PT16VTJ pinout, MC9S08PT16VTJ application, or MC9S08PT16VTJ equivalent, this page delivers verified specifications, package mapping to 20-pin TSSOP, validated peripheral timing, low-power stop3 mode current (1.3 µA), and real-world use cases in HVAC actuation, smart metering, and automotive body electronics.
Technical Context
The MC9S08PT16VTJ implements an S08 CPU core with nested interrupt support (up to four levels) and 40 interrupt/reset sources. Its clock system combines a 31.25 kHz–20 MHz external crystal oscillator (XOSC) and an internal clock source (ICS) with FLL, enabling precise 1% frequency stability (0–70 °C) and 2% over full temperature range.
System protection includes independent watchdog timer, programmable low-voltage detect (LVD) with four warning thresholds (2.56–4.8 V), illegal opcode/address detection, and flash/RAM access protection. Debug is supported via single-wire background debug interface (BKGD) with three breakpoints and on-chip ICE module featuring two comparators and nine trigger modes.

FAQ
What is the maximum operating frequency and voltage range for the MC9S08PT16VTJ?
The MC9S08PT16VTJ operates at up to 20 MHz bus frequency across a supply voltage range of 2.7 V to 5.5 V, fully specified over the industrial temperature range of –40 °C to 105 °C. This ensures deterministic timing in battery-powered and automotive-grade applications where voltage fluctuation and thermal stress are common. The internal clock source (ICS) with FLL maintains frequency accuracy within 2% across the full temperature range.
Does the MC9S08PT16VTJ support in-circuit debugging, and what interface is used?
Yes, the MC9S08PT16VTJ supports in-circuit debugging via a single-wire background debug interface (BKGD) on pin PTA4. It provides three hardware breakpoints, on-chip ICE debug module with two comparators and nine trigger modes, and supports force-reset entry into BDM mode. This eliminates the need for dedicated JTAG headers, simplifying PCB layout and reducing debug footprint in space-constrained 20-pin TSSOP designs.
How does the MC9S08PT16VTJ manage power in low-energy applications?
The MC9S08PT16VTJ achieves ultra-low power consumption through its Stop3 mode, drawing just 1.3 µA at 3 V with only the 1 kHz LPO clock active. Peripherals like the ADC, TSI, and LVD can be selectively enabled in Stop3, adding ≤128 µA total. Clock gating via the peripheral clock enable register further reduces dynamic current, making the MC9S08PT16VTJ ideal for battery-operated sensors and meters requiring multi-year operational life.
What analog peripherals are integrated into the MC9S08PT16VTJ?
The MC9S08PT16VTJ integrates a 12-channel, 12-bit ADC with 2.5 µs conversion time, an analog comparator (ACMP) with independently configurable rising/falling edge interrupts and filtering, and a buffered bandgap reference (1.16 V ±20 mV). These are fully operational in Stop3 mode, enabling continuous sensor monitoring without waking the CPU-critical for thermal cutoff, battery voltage supervision, and touch-button wake events.
Is the MC9S08PT16VTJ pin-compatible with other members of the S08PT family?
No, the MC9S08PT16VTJ in 20-pin TSSOP is not pin-compatible with other S08PT variants such as the 44-pin LQFP (MC9S08PT16VLD) or 32-pin LQFP (MC9S08PT16VLC). Pin assignments differ significantly across packages due to I/O multiplexing and peripheral mapping constraints. Migration requires PCB redesign; however, firmware is largely portable within the S08PT family due to consistent register architecture and instruction set.
